Understanding how the body responds to Hepatitis Delta Virus infection

Official title: Host Response to Hepatitis Delta Virus Infection

Funded at University of Southern California · NIH-11168217 · Data updated 2026-11-12

This study is looking at how the Hepatitis Delta Virus (HDV) affects the immune system in people who also have Hepatitis B, to find out why it makes liver problems worse and to discover new ways to help manage HDV infections.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals who are co-infected with Hepatitis B Virus and Hepatitis Delta Virus.

Less likely to help

Patients who are not infected with either Hepatitis B Virus or Hepatitis Delta Virus will not benefit from this research.

What this research studies

This research investigates the immune response to Hepatitis Delta Virus (HDV) in individuals who are also infected with Hepatitis B Virus (HBV). It aims to uncover the mechanisms by which HDV exacerbates liver inflammation and accelerates the progression to severe liver disease. The study will utilize genetic and biochemical approaches to analyze how HDV interacts with the immune system, particularly focusing on the activation of antiviral genes. By understanding these processes, the research seeks to identify potential therapeutic targets for better management of HDV infections.

Why it matters

Potential benefit: If successful, this research could lead to the development of effective therapies for patients suffering from HDV and HBV co-infection, potentially improving liver health and patient outcomes.

How similar studies have gone: Previous research has shown promising results in understanding viral infections and immune responses, but this specific investigation into HDV is relatively novel.
